The median income in Knightdale increased from $63,451 in 2013 to $70,778 in 2022, representing an 11.5% growth. This economic improvement coincided with demographic shifts, particularly the increase in Black plurality and growth in Asian and multiracial populations. The city's population grew by 31.8%, from 27,003 in 2013 to 35,594 in 2022.

Knightdale's demographic shifts align with trends seen in many U.S. suburban areas, where increasing diversity and racial integration are becoming more common. The economic growth and population increase suggest that Knightdale may be part of a wider trend of suburban expansion and diversification often observed in areas surrounding major metropolitan centers.

Based on observed trends, Knightdale is likely to continue its trajectory towards greater diversity. The city may transition from "Moderate Diversity" to "High Diversity" within the next decade if current trends persist. The growing Asian and multiracial populations, combined with established Black, White, and Hispanic communities, could lead to a scenario where no single group comprises more than 40% of the population, and at least three groups have significant representation (over 10% each).

If the economic growth trend continues, further increases in median income may be expected, potentially attracting more diverse, affluent residents. However, it will be important to monitor how this growth impacts housing affordability and community dynamics.

Knightdale appears to be on a path of increasing diversity and economic growth, potentially evolving into a more complex and multicultural suburban community in the coming years. This transition could bring both opportunities and challenges as the city adapts to its changing demographic landscape.
